SPECIIEICA'IION forming part of Letters Patent No. 760,742., dated May 24,1904; l Application filed November 3(7), 1903. Serial No. 183,188. (Nc model.) i i.

Too/ZZ whom/72# may concern: i

Be it known that we, SAMUEL Y. KENNEDY, and CHARLES S. SHARP, citizens `of theUnited States, residingat Auburn, inthe county of Cayuga and Stateof New York, have invented certain new and useful Improvements in Disk Harrows, of which the following is aspeciication. v. f

The object of our invention is to provide a scraper for disk harrows that is simple in construction 4and eEective in dislodging any mat terthat may adhere to and clog the disks.

' Referring to the drawings, Figure 1 is a rear A represents the frame-bar of a disk hare' row, towhich is suspended a gang of disks mounted vupon an axleiand spacedin the ordinary manner.`

B is a scraper-bar. mounted in slots b3 in, brackets c a on the frame-bar A. Y

The Scrapers C are preferably made of sheetsteel, their lower4 ends being beveled to'secure a better and more effective cleansing of they on the castings D and the scraper-blades C are springs c, holding the latter in againstlips or offsets c', which engage with the lower ends of the slots in the scraper-blades.

The scraper-blades when in a normal posi, tion are not in direct contact with the faces of thc disks, but must be moved into opera# tive contact: beforelthey are rocked to cleanse the disks of adhering matter. Consequently the 'scraper-bar B has a longitudinal as well as a rocking movement, which it receives through 'the operation of levers, as will now be de- 'gles to form a handle and itslower en d bent similarly with `an eye formed 4at its extremity in which'is hooked a link e, an end of saidv i.

link passing through an eye f on the bracket a, the play of the link in one direction'being regulated by adjustable nutse. Itl will be seen that notwithstanding the levers E and F 'are connected they do not interfere one kwith lever whose fulcrum is the point of connection Withthe'link e. 'The scraper-bar is moved hori- V zonta1ly,'carryingthe scraper-,blades intoforcible contact with the concave faces of the disks. l

rlfhe full movement of the lever Fcarries the hookend of the link e'above the horizontal plane of the eye f on thebracket a. and the f lower bearing f of the lever F, as shown inv Fig. 3. The back pressure of the scraper-blades and also thepsprings c tends to keep the lever locked in this position.v The lever E is then rocked, swinging the scraper-blades across the faces ofthe disks from center to periphery and the reverse, as shown inFig. 2, completely removing any adhering material. By rotating the lever F to its normal position the back pressure of the scraper-blades and the springs c will force the scraper-bar and scrapers back to their inoperative position.

Having thus described our invention, what we claim is- 1. In a disk harrow, the combination witha 'gang of rotary disks, of a frame supported thereon, av sliding and rocking scraper-bar supported by the frame, a series of scraperblades mounted on the bar, means controlled by the driver for sliding the bar endwise to throw the Scrapers into contact with the disks, Y

and separate means also under the drivers control for rocking the bar to cause the scrapers to sweep across the disks.

2. In a disk harrow the combination with a gang of rotary disks, of a frame supported thereon, a rocking scraper-bar supported by the frame, a series of slotted scraper-blades mounted on the bar, and notches in said bar with which the slots of the scrapers engage.`

3.v In a disk harrow the combination witha gang of rotary disks, of a framesupported thereon, a rocking scraper-bar supportedby the frame, notches in said bar, a series of slotted scraper blades through which the bar passes, said slots and notches engaging to hold the upper ends of the scraper-blades in place.-

4. In a disk harrow the combination with a gang of rotary cutting-disks, of a rocking scraper-bar having notches therein, slotted scraper-blades mounted thereon, the upper ends of the slots engaging with the notches in the scraper-bar, and castings on said bar having arms projecting through the slots in the scraper-blades and engaging therewith.

5. In a disk harrow the combination with a gang of rotary disks of a rocking scraper-bar having notches therein, slotted scraper-blades mounted thereon, castings on said bar having arms projecting through the .slots in the scraper-blades and engaging therewith, and springs 'on said arms bearing against the blades.

6. In a disk harrow the combination with a gang of rotary disks of a rocking scraper-bar having notches therein, slotted scraper-blades, the upper ends of the slots engaging the notches in the scraper-bar, castings on said bar having arms projecting through the slots in the scraper-blades, catches on said arms engaging with the lower ends of the slots, and springs on the arms bearing against the scraper-blades to hold the latter in normal working position.

' 7. In a disk harrow, the combination with a gang of rotary disks, of a rocking and sliding scraper-bar, slotted scraper-blades mounted thereon, a lever for sliding the bar endwise to throw the scraper against the disks, and a separate lever for rocking the bar to throw the scrapers across the faces of the disks.

8. In a disk harrow, the combination with a gang of rotary disks, of a sliding and rocking scraper-bar, slotted scraper-blades mounted thereon, a lever for moving said scrapers towardthe disks, and a separate lever for rocking the scraper-bar to swing the scra1 er-blad es across the faces of the disks and in contact therewith. v

9. In a disk harrow the combination with a gang of rotary disks, of a frame supported thereon, brackets on the frame, a rocking scraper-bar movable in saidbrackcts, a series of Scrapers carried by the scraper-bar, an actuating-leveren said bar,a rotating lever jonrnaled on the actuating-lever, and a link connecting the rotating lever with the bracket.

l0. In a disk harrow the combination with a gang of rotary disks of a scraper-bar, scraperblades mounted thereon, an actuating-lever, and a rotating lever for moving the scraperblades into engagement with the disks.

1'1. In adisk harrow the combination with a gang of rotary disks, of a scraper-bar, a series of Scrapers mounted thereon, an actuating-lever to swing said scrapers, a rotating lever journaled thereon and operated to move and lock the Scrapers into engagement with the disks.

12. In a'disk harrow the combination with the disks, of a scraper-bar, a series ot' slotted Scrapers mounted thereon, an actuating-level', a rotating lever journaled thereon and a link connecting said rotating lever with the frame.

i In testimony whereof we hereunto set our hands, this 19th day of November, 190i), in the presence of two attesting witnesses.
